External mastic for homes and businesses in Ruislip Manor
For buildings in Ruislip Manor, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on façade panels, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are movement joints with cracked, split or missing sealant and panel joints letting water in.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. For a flat in Ruislip Manor, check the lease for who looks after the outside.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Walls and rooflines in Ruislip Manor
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Ruislip Manor is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Managing a site like Lady Bankes Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant is not too deep.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.
Signs you need external mastic in Ruislip Manor
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
Signs it’s time to call us include:
- Panel joints letting water in
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
- Weeds or debris growing in open joints
Homes close to Church of St Paul include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
Before you book anyone
- Whether the sealant suits the joint
- What preparation is included
- Is the old sealant removed completely?
- What the cure time is
What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Ruislip Manor. It helps if you can point us to a visitor permit or a bay close to the door.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us if parking is tricky
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Ruislip Manor questions
Is parking a problem for a job in Ruislip Manor?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords with property near West Ruislip station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job.
Do you come to Ruislip Manor?
Yes, we do. Our applicators work in Ruislip Manor, and the service is the same as everywhere else.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Ruislip Manor, the repair is bigger than the sealant job would have been.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
